(Tulsa, OK) -- Injunction denied. A federal judge is refusing the state's request to stop 13 companies from spreading chicken waste in the Illinois River watershed.Judge Gregory K. Frizzell wrote that the state "has not yet met its burden of proving that bacteria in the waters of the IRW are caused by the application of poultry litter rather than by other sources, including cattle manure and human septic systems." The state is suing the companies with the claim that the spreading of manure in the watershed is causing harm to the environment.
